WELL-DRILLING MACHlNE.

EEPEGIFICATION forming part of Letters Patent No. 291,837, dated January8, 1884.

Application filed May 16, 1883. (No model.)

1'0 all whom, it may concern Be it known that 1, WILLIAM E. BROWN, ofthe town of Elbridge, in the county of Onondaga, in the State of NewYork, have invented new and useful Improvements inWVell-DrillingMachines, of which the following, taken in connection with theaccompz-tnying draw-- ings, is a full, clear, and exact description.

This invention relates to that class of drilling-machines which areusually employed for drilling wells through rock and other hardsubstances. 7

Theinvention consists in an improved organization of the actuatingmechanism of the drill and the supporting-frame thereof, whereby amachine of superior efficiency with great convenience of operation isobtained, all as hereinafter more fully described, and specifically setforth in the-claims.

In the accompanying drawings, Figure l is a side view of my improvedwell-drilliug machine with its parts placed in position fortransportation. Fig. 2 is a view of the opposite side of said machine,showing it in its operative position. Fig. 3 is a detail view of thedrill-dropping lever, showing its relation to the rope-drum and cam.Fig. 4: is a detached plan view of the aforesaid lever. Fig. 5 is a planview of the machine, taken on line a a', with the braces removed, tobetter illustrate the mechanism; and Fig. 6 is a front elevation of themachine.

Similar letters of reference indicate corresponding parts.

A represents the base of the machine, mounted in the form of ahorizontal frame on a suit able truck or vehicle, to render the machineportable.

To each end of .the base A is secured an upright, B B, sustained bybraces G 0, running from the rear end of the base to the upper part ofthe forward frame, B, and by girders D D, extended from the centralportion of the braces O to the posts of the aforesaid frames, saidbraces and girders forming the support for the bearings of the shaftsand drums of the machine.

S denotes the shears erected on the end of the machine, and carrying ontheir upper end the pulleys N and 0, over which the drill-rope Randslush-pump rope It are extended. These shears l hinge to the top of theframe B in such a manner as to allow them to be swung over and down ontothe frame B, as illustrated in Fig. 1 of the drawings, therebyplacing'them in a convenient position for transportation when not inuse. The foot of the shears is extended to the base Aland adj ustablysecured thereto, as hereinafter described.

' E E are braces hinged to the side of the upper portion of the shears,and when erected the foot of said braces rest on the rear end 'of thegirder D, and are detachably secured thereto, so that they can be foldedclose to the side of the shears when laid down in the man-.

the frame B, and thus raise the shears to their upright position, asshown in Fig. 2 of the drawings. A dog, 9, engages the pinion f andprevents the reverse motion thereof, and maintaining the rope R woundupon the shaft F. a is the shaft or drum 011 which the drillrope It iswound, said shaft being provided on each end with a spur-wheel, 1),serving as heads for the drum. A shaft, to, arranged pa allel to theshaft a, is provided with two pinions, b, meshing in the gears orspurwheels 1). One end of the shaft (9 is provided witha hand-crank, c,for transmitting motion to the shaft a, to wind up the drill-rope B whenre quired for raising the drill connected to the said rope, the drillbeing lowered by releasing the crank, the weight of the drill drawingthe rope off the shaft a, and the run of the rope being controlled bymeans of a brakepulley, h, attached to the shaft a, and abrakelever, h,pivoted on the frame-work, and bearing 011 the periphery of thebrake-pulley.

To the opposite end of the shaft a is attached a.ratehet-wheel, 7:, withwhich engages a dog, 7.1, for the purpose of preventing the reversemotion of the shaft a, and the resultant unwinding of the rope duringthe operation of the machine, said dog" being thrown out of erates.

engagement with the ratchet when the ropeR is to be given out to lowerthe drill.

At the outer side of the ratchet-wheel is a pulley, h, which is mountedloosely on the shaft a, and back of the pulley is a clutch, p, whichslides on a spline on the shaft, and is adapted to engage or interlockwith the side of the pulley, the arrangement of said clutch being socommon as to not requirea special illustration in this case. It may,however, be seen in Figs. 5 and 6 of the drawings. By means of a lever,g, pivoted on the side of the wooden frame of the machine, the clutchcan be thrown in and out of connection with the pulley. The latter isconnected by a belt, m, with another pulley, L hereinafter described,and by throwing the clutch into engagement with the pulley h the drum orshaft a can be revolved to wind up the rope R and raise the drill by themotor .of the machine.

H represents the lever which, in conjunction with the cam G, imparts thedropping or plunging action to the drill when in operation, said actionbeing due to the rope It being extended from the drum or shaft a to thesheave (Z on the free end of the lever H, and thence over a sheave 011the upper end of the shears S to the drill, and the sudden release ofthe same allowing the drill to drop. The lever H, I hinge on the frameof the machine in such relative position as to bring the hinged end ofthe lever in proximity to and as near as possible in the same horizontalplane as the rope-drum a, thereby obtaining a constant bearing of therope It on the foot of the lever during the movement of the lever, andtherefore leaving the sheave d, which is pivoted near the free end ofsaid lever and carries the rope It, dormant on its axes during the movement of the lever, whereas in other analogous drilling-machines theaforesaid lever has been so arranged that the motion of the leverproduced an oscillating motion 011 the sheave d, and consequently moreor less wear and abrasion of the rope and sheave.

In order to bring the sheave d as near as possible to the under side ofthe lever H, I construct the lever of two parallel scantlings properlybraced and tied together, with a space between them, forming alongitudinal slot, at, in which the sheave (Z is pivoted by a pinpassing transversely through the lever and sheave.

At the extremity of the lever H a roller, 0, is pivoted in the slotn,which roller forms an anti-friction bearing, on which the cam G op-This cam is fastened to a counter shaft, 0, and made in the form of asemicircular or segmental arm, the lever H being of such length as tobring the roller 0 to'bear on the cam G near the attached end thereof,when said cam is raised, as shown in Fig. 3 of the drawings, therebyobtaining the maximuni power with theminimum motion at the beginning ofthe action of the lever. In the descent of the cam Gr it depresses thelever H wit-h gradually accelerated speed until it finally draws its endoff from the roller 0 and releases the lever H, the depression of thelever causing a draft on the rope R, and thereby raising the drill, andthe aforesaid sudden release of the lever allowing the drill to drop,thus producing the requisite act-ion for drilling wells.

It will be observed that by the arrangement of the roller 6 on the endof the lever H the cam G invariably receives its bearing at that point,and thus obtains the greatest purchase, and actuates thelever withoutproducing jars, while in other analogous machines the roller is pivoted011 the cam and travels back and forth 011 the lever, and thus in manyinstances produces jars on the lever and drill-rope. The counter-shaft 0has attached to it a gear-wheel, 1?, in which meshes a pinion, 1?, onthe main driving-shaft 0, the latter being provided with the maindriving-pulley M, which is connected by a belt, .9, with thesteanrengine or other motor.

R represents the rope which is connected to the slush-pump 'U, forlowering and raising the same in the well, said rope passing over asheave, O, on the upper part of the shears, in the usual manner, andthence extends to and is connected with a drum, K, which is mounted inhearings or boxes attached to the upper or forward end of the sidebraces, G C. The journal-bearing l of one of the boxes M is elongated,to allow the drum to swing laterally. The journal which lies in theaforesaid bearing projects at the outside of the box, and with theprotruding end is connected a lever, V, which is fulcrumed on the frameof the machine.

A pulley, L, on the end of the drum K, is connected by a belt, J, with apulley, T, on the counter-shaft 0. Said belt -is of such length that theaforesaid lateral swinging of the drum K will tighten and slaeken thebelt; hence by proper manipulation of the lever V, connected with thedrum, the latter can be set in motion to wind up the slush-pump rope R,and raise the slush-pump out of the well; or the belt can be slackened,so as to allow the rope to unwind from the drum and the pump to descendinto the well, as may be desired.

0' represents a stop in the form of a plate at tached to the frame ofthe machine and held normally over the lever H when depressed, so as toretain the lever in a dormant position when desired.

A cranked rod, 1', is arranged on the side of the'machine and connectedwith the stop 9- in such a manner that by turning the cranked rod thestop is drawn out of the path of the lever,to allow the latter to resumeits operation with the cam G.

Having described m y invention, what I claim as new,and desire to secureby Letters Patent, 1s-
